摘 要:
通过2D NMR技术对5个2，4，8，10-四卤代-6-硫-12-H-双苯并[d，g][1，3，2]-二氧磷杂八环的^1H和^13C NMR信号进行了准确的归属，获得了所有芳环碳原子的P-C和部分质子的P-H偶合常数，3／9位质子的^5JPH属于折线型偶合，偶合常数为0．9～1．0Hz．[著者文摘]

Abstract:
The ^1H and ^13C NMR signals of 2,4,8, 10-tetrahalogen-6-thio-12H-dibenzo [d,g][1,3,2]-dioxaphosphocins were assigned with 2D NMR techniques. The P-C coupling constants for all aromatic carbons and the P-H coupling constants were obtained, among which the ^5JPH coupling constants was in the range of 0.9-1.0 Hz for protons at C-3/C-9 （zigzag coupling）.[著者文摘]
